The East African Rift is one of the great tectonic features of Africa, caused by fracturing of the Earth’s crust. This astronaut photograph of the Eastern Branch of the Rift (near Kenya’s southern border) highlights the classical geologic structures associated with a tectonic rift valley.

“Textbook” horst and graben formation (left) compared with actual rift terrain (upper right) and topography (lower right). Notice how the width taken up by the trapezoidal areas undergoing normal faulting and horst and graben formation increases from top to bottom in the left panel. Rifts are considered extensional features (continental plates are pulling apart) and so often display this type of structure. Credit: James Wood / Alex Guth. (via geology.com)

Mount Kilimanjaro’s peak in north-eastern Tanzania captured by the US-operated GeoEye-1 satellite. Mount Kilimanjaro rises from the plains to an elevation of 5,895 metres, the highest in Africa and the world’s largest free-standing mountain - it is also an active volcano.

Cape Town and the Cape of Good Hope, South Africa, appear in the foreground of this perspective view generated from a Landsat satellite image and elevation data from the Shuttle Radar Topography Mission (SRTM). The city center is located at Table Bay (at the lower left), adjacent to Table Mountain, a 1,086-meter (3,563-foot) tall sandstone and granite natural landmark. (via NASA Earth Observatory)

Article Images Earth from Space: Somali bouquet (by europeanspaceagency) The bouquet-resembling landscape of the Gedo region in southwest Somalia is featured in this image acquired by ALOS, Japan’s four-tonne Earth observation satellite with its Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2) instrument. This spectacular scenery lies some 400 km west of Mogadishu and 800 km north of Nairobi. Credits: JAXA, ESA.
